Biofeedback in Grandmothers Raising Grandchildren: Evaluating Intervention Parameters

Evaluation of Prevention Programs for Grandparent Caregivers: a Systematic Review

This systematic review critically evaluates 21 grandparent-focused prevention programs designed to benefit grandparent caregivers or target grandparent caregivers as agents of change for grandchild development. These grandparent programs were published in 35 peer-reviewed articles in the last 31 years. For each program, we described the phase of development of program (i.e., feasibility, pilot, and efficacy), delivery characteristics, and adaptations of existing evidence-based programs to meet the needs of grandparent caregivers in diverse sociocultural backgrounds. For programs tested under a controlled trial design, we evaluated core components and preliminary effects on targeted outcomes. Most studies targeted grandparents who served as primary or custodial caregivers in the USA, while limited studies targeted supplementary grandparent caregivers. Thirteen programs which were evaluated using pretest-posttest designs demonstrated feasibility and acceptability of the grandparent programs. Moreover, eight programs which were evaluated using randomized-controlled trials (RCTs; 5 pilot and 3 full-scale efficacy trials) demonstrated promising outcomes. Additionally, we identified six core components and 17 specific elements in eight programs evaluated using RCT designs. Overall, we provide a comprehensive critique of this body of literature as well as directions for future studies, including the need to develop programing tailored to grandparent caregivers with unique needs.

Heart rate variability biofeedback: implications for cognitive and psychiatric effects in older adults

OBJECTIVES

Two decades of heart rate variability (HRV) biofeedback research have focused on adolescent and adult populations with a variety of symptoms and conditions at the exclusion of older adults. This study explores HRV biofeedback as a novel treatment to decrease psychiatric symptoms and improve cognitive functioning in older adults.

METHODS

Participants enrolled in a three-week intervention that included six 30-min biofeedback sessions. Neuropsychological and psychiatric measures were administered before and after the intervention.

RESULTS

Decreases in depression (Cohen's d = 1.02, p < .001), state anxiety (Cohen's d = 0.82, p = .003), and trait anxiety (Cohen's d = 0.84, p = .002) were observed. An increase in attentional skills as measured by the Trail Making Test - Part A was seen (Cohen's d = 1.00, p = .001). Differences in executive skills as measured by the Trial Making Test - Part B and the Stroop Task did not reach statistical significance.

CONCLUSION

This study suggests that older adults may benefit from HRV biofeedback interventions much like the younger populations that have been studied for decades. Depression, anxiety, and attentional skills were positively affected. Several participants reported improved sleep quality and stress management. Future studies should corroborate these findings.

Comprehensive evaluation of interventions: eight vital parameters

BACKGROUND

It is critically important to determine the effectiveness of an intervention before it can be translated into clinical practice. However, the future implementation and sustainability of the intervention may be diminished if other intervention parameters are not assessed. This requires obtaining feedback from intervention recipients so interventions will be perceived as appealing, relevant, meaningful and beneficial to them; otherwise recipients may be unlikely to perform them over time, resulting in unsuccessful health outcomes.

AIM

To propose the addition of two intervention parameters to the existing six-parameter model and provide examples from recent research of how each parameter can be tested.

DISCUSSION

Definitions of the eight parameters are provided and methods for analysing each of them explained. While some studies show necessity, fidelity and cost have unique distinguishing characteristics, other studies indicate feasibility, acceptability and safety have common features, and efficacy and effectiveness are closely associated.

CONCLUSION

Researchers frequently examine one or two parameters, but few simultaneously apply the six-parameter model. This model is also missing two vital parameters - efficacy and cost.

IMPLICATIONS FOR PRACTICE

Comprehensive and systematic evaluation of all eight intervention parameters is recommended before researchers begin randomised controlled trials and translate them into practice.
